Everyone 'knows' that Mac games sell a tiny fraction of the amount that Windows games sell, and that Linux games simply don't exist. But are these ideas based on reality? Where did these figures come from? Anyone who has ever worked with statistics knows that it's unwise to trust 'common knowledge' without data to back it up. I decided to ask some developers about their sales distribution, and get some real data about Mac and Linux game sales."
